A Efficacy of F-QLED651nm tested against MDR S. aureus under MB concentration of 100 μM and 1-h illumination. B Efficacy of F-QLED651nm against MDR P. aeruginosa under MB concentration of 100 μM and 1-h illumination. C Efficacy of F-QLED629nm against MDR S. aureus under PpIX concentration of 1 mM and 36-min of illumination. D Efficacy of F-QLED629nm against MDR E. coli under PpIX concentration of 1 mM and 2-h illumination. The tested F-QLEDs include the best-performing 651nm F-QLEDs (F-QLED651nm) and 629nm F-QLEDs (F-QLED629nm), while the photosensitizers were MB for the F-QLED651nm and PpIX for the F-QLED629nm, respectively. All tests were performed by driving the F-QLEDs at a constant voltage of 4.5 V. Asterisks (*) indicate cases where bacterial survival was undetectable. The mean of each treatment group was compared to the control group using a t-test. Statistical significance is shown as follows: NS (not significant), * (P < 0.05), and ** (P < 0.01).
